DFT Insight Into Physical Properties of Halide Ions Replacements in Oxo‐Selenate Halide Compounds for Photovoltaic Application

Energy Science &Engineering, EarlyView.
Using density functional theory (CASTEP, GGA–PBE), the structural, electronic, optical, and mechanical properties of YSeO₃X (X = F, Cl, Br, and I) compounds are systematically investigated. The materials have exhibited structural stability, tunable band gaps, strong optical absorption, anisotropic ductile behavior, and promising potential for ...

Machine Learning‐Driven Classification and Production Capacity Prediction of Tight Sandstone Reservoirs: A Case Study of the Taiyuan Formation, Ordos Basin

Energy Science &Engineering, EarlyView.
On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...

Study on Damage Characteristics and Evolution Law of Macro‐Meso Structure of Surrounding Rock Under Mining Stress

Energy Science &Engineering, EarlyView.
Investigating the differential impact of mining stress on roadways, we find that in horizontally stressed environments, the inner surrounding rock exhibits more pronounced macro‐meso damage compared to the outer side. ABSTRACT The control of surrounding rocks in dynamic pressure roadways has consistently been one of the challenging predicaments in the ...

Experimental Investigation of Sensitivity for Coal and Gas Outburst Risk Prediction Indexes in Raw and Tectonic Composite Coal Seams

Energy Science &Engineering, EarlyView.
A comparative study was conducted on gas desorption laws of raw and tectonic coals. The sensitivity of regional and local outburst prediction indexes was compared. Gas content is more sensitive than gas pressure for composite coal seams. K1 can more accurately predict the outburst danger than Δh2 $\Delta {h}_{2}$ in composite coal seams.

Interpretable Tree‐Based Models for Predicting Short‐Term Rockburst Risk Considering Multiple Factors

Energy Science &Engineering, EarlyView.
Interpretable tree‐based models integrate microseismic, geological, and mining indicators to predict short‐term rockburst risk. SHAP analysis reveals the dominant role of energy‐related features and clarifies nonlinear factor interactions, enabling transparent and reliable early‐warning in deep coal mines.
